To all'wiw'm' concern: the novcl construction herein described ,Be it known that LBBR AKIKO. Swn nillustrated inlthe' draivin wherein I his: Burr, a. of the United States, residshown an embodiment o the invention, it ing at Akron; the countyof Summit and hem understood that the invention is not Statefof Ohiojhave invented'newand useful co nod to the articular embodiment pm en s n hio f fiflfi which ow u is capab le of various ada tions the following'isaffspecifiation. and that changes, variations and mo This invention to" certain new and (cons may be made which come within the m in; 1; ements in elastictires 1501 see c of the claims hereunto appended. wheelsan particular'.relation imthe drawingw 'ch forms a part hereofproved cushion tire'wliichmay be used to Ihave shown a single figure which is a peradvantageflon the whels'oLautomobiles, spective view of a. portion of a tire contru'c'ks'or other-[Vehicles Structed in a ordance with this invention It is an object ofi-the ,myelitionto proand I have employed like characters of refervide a'tire body of simple,'economical can once to designstegthe some or similar arts struction which when .employedonwheels' or things as the same occur at di crent will be exceedingly durab e', and W111 propoints in the tire. vide an eflicient cushion therefo The particular adaption of the invention It is a further object of the inventlon to shown comprises an annular body 1, preiprovide a tire composed of rubber, rubber erably composed of elastic rubber and havcomposition or the like which is rendered mg a hard rubber hose 2, which is vulcanmore readily compressible by having openized to a suitable rim 3. The numeral 4 is ings which extend through the tire body used to denote the peripheral or tread face from one lateral side to e other and arof the tire and the numerals 5 and 6 the ranged at an inclination to the axis of the lateral sides thereof. The lateral sides are the so that water, sand or other substance inclined toward eachother and th base 2 angle to each other and will be expelled therefrom by centrifugal of the tire is relatively wider than the tread force when the tire is in motion and sot at face 4. The lateral side 6 is curved at its such substance will be drawn therefrom by outer circumferential edge 6" to meet the the force of gravity when the tire is not in tread face 4 and the outer circumferential motion. edge 5 of the lateral side 5 is likewise A still further object is to provide a tire curved to meet the said tread face. The tire body having a plurality of openings arbody is provided with a. ciroumferentially ranged transversely therethrough with the extendmg series of holes or openings 7 and axes of adjacent opening disposed at an 8wh1ch extend transversely through the tire thereby provide body at an inclination to the axis of the a tire body having areas of greater comtire. The said openings 7 and 8 are posipressibility which are uniformly distributed tioned in the tire body 1 in alternate relation throu hout the tire. and are alike in form, diflering only as to A firther ob'ect lies in the provision of the an is at which they project through the a tire body 0 the class above indicated tire bo y. Eachopening 7 is formed in the which is provided with ventilating passages tn'e body so as to extend through the tire arran d therein to provide a large amount from a point adjacent the inner edge of the of ra iating surface and to thereby provide lateral face 6 to a point adjacent the outer a tire which may be run at high speed witl1- edge 6 of the a'lteral face 5. out being injured by overheating. Each openin 8 extends through the tire An additional object is to provide a tire from a point a jacent the inner ed e of the having transverse openings an'anged at an lateral face 5 to a point adjacent t c outer inclination therethroughso as to increase edge 6" of the lateral face 6. All of the 1 5 the length of the openings and lessen the openings 7 are inclined at a similar angle to amount of rubber necessary to be used in the axis of the tire and the openings 8 are the construction of the tire without in any oppositely disposed at a similar angle to way detracting from its strength or stasaid axis so that the axis of each opening 7 bility, is disposed at an angle to the axis of the ad- 0 The above and additional objects are no jacent openi s 8. The openings 7 and 8 complisbcd and other ends are attained by as shown in t o drawings are in the form of cylindrical bores, but it is to be understood that the iiailiventhin is not confined to an particu ar e o opemn t is also to be dnderstood tl iet while I have shown a preferred form of rim with the tire vulcanized thereto that the tire may be used with any form of rim and be secured thereto in any desired manner.

The cross sectional contour of a tire construoted in wool-dance with this invention met-{be varied'to adapt it to various uses no the-invention is not strictly confined to the Hgerticular shape of tire shown.

. ving thus stated the objects of the'invention and described the same in detail, I claimasnew and desiretoeewrebyLettors-Patent:

1. A euehion'tire comprising an annular elastic body provided with a circumferent-ielly extend seriesof holes which extend transverse y therethroufilsi, with the axes of the holes altemately at an opposite angle to the axis of the tire.

2. A cushion tire comprising an annular elastic body provided with a plurality of hole eaoh extending transversely therethrough at an inclination to the axis of the tire.

8.- A cushion tire comprising an annular elastic body provided with e circumferentially extending seri of regularly recurring holes each extending transversely themhroflgh at in inclination to the axis of the tire and with alternating holes oppositelyinoline 4. A cushion the of the class described, having inolined lateral sides and provided with t cireumzforent ially enemas of straight boxes which extend at an inclination to the axis 1 front-one lateralfaoeofthetireto eotherllteral face thereof.

5.111 a tire oithe c198 m annular elastic Body, a plurality of laterally bores extendi therethrough at an inclination to the axis t ereof and in spaced relation to the tread face thareoi.

In testimony whereof I have hereunto set my hand.
